Rotavirus Vaccinations for Babies Also Reduce Disease in Older Children, Adults
Regular rotavirus vaccinations for babies have also helped lower the rate of rotavirus-related hospitalizations for older children and adults since 2006, according to a new study in the Journal of the American Medical Association. Rotavirus can cause gastroenteritis, leading to severe diarrhea, vomiting, fever and abdominal pain. Ben Lopman, who worked on the study at the U.S. Centers for Disease Control and Prevention, told Reuters that the improved rates for older children and adults was an unexpected benefit of the vaccinations. An oral form of the vaccination became routine in 2007, after which rotavirus-related hospital discharges dropped by 70 percent for children ages 5-14, by 53 percent for people ages 15-24 and by 43 percent for adults ages 25-44. "This is one example of what we call herd immunity," he said. "By vaccinating young children you prevent them from getting sick, but you also prevent them from transmitting (rotavirus) to their siblings and their parents." Read more on vaccines.
Report: Fewer Kids Illegally Buying Tobacco Products
The Synar Amendment Program was started 16 years ago in an effort to prevent the sale of tobacco products to people under the age of 18. A new report from the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) shows that it’s working, with only about 9 percent of retailers violating the ban, the second lowest rate since the law was enacted and far better than SAMHSA’s goal of 20 percent. In addition, 33 states and the District of Columbia now have local violation rates below 10 percent; and nine states have statewide violation rates below 5 percent. Still, Frances Harding, director of SAMHSA's Center for Substance Abuse Prevention, said that "Far more needs to be done to prevent kids and young adults from using tobacco, which is still the nation's leading cause of preventable death.” Read more on tobacco.
High Cholesterol Levels Dramatically Increases Heart Attack Risk in Middle-aged Men
While high cholesterol levels are dangerous for both men and women, middle-aged men with high levels have three times the risk of heart attack, according to a new study in the journal Epidemiology. Lead researcher Erik Madssen, MD, of the department of circulation and medical imaging at the Norwegian University of Science and Technology, said this means men with high cholesterol levels should be receiving more aggressive treatment than is currently common. The reason for the difference in risk still isn’t known, though Madssen said one possibility is the positive effects of estrogen. Both men and women can reduce the risk of heart attack by making lifestyle changes such as improved diet and exercise, as well as through medication; preventative efforts are especially important for people with a family history of heart disease.
